My Jaguar S type 2.7d has been losing a little coolant. I gave it a thorough inspection today, removing the lower cover, air filter etc.
It seems the coolant is leaking from the passenger side of the engine and there is some of it leaking down this pipe here
This appears to be a coolant metal pipe which joins to rubber pipes at the bottom and near the top of the engine. I have looked near the top join but there doesn’t seem to be any leaking however, there is a metal thing sticking out from the engine about half way up which has coolant on it and it almost touches this pipe. I am not sure what it is because I cannot see it from the top at all and visibility from the bottom is poor, it is on the passenger side of the engine. I did wonder if it is a thermostat housing or something? If anyone has any advice it would be gratefully appreciated. Here it is.
